Ghostly Matter

Professor Penderghast, the world's leading expert in the capture of ghosts and other supernatural creatures, receives a desperate cry for help over the radio: it's Melvil, his old friend and colleague.
All clues lead to the mysterious Blackwood mansion: an estate located in a remote area of northern Scotland, which is said to be afflicted by a terrible curse. Guide the professor through the darkness and solve the mystery of the haunted house as you try to find out what happened to your missing friend. Solving puzzles, exploring, collecting items and uncovering a mystery form the basis of the game; but there will be no shortage of deadly weapons and explosions, disgusting enemies popping up everywhere and frenetic action.
The first game from the Small Bros studio and developed by single person, Ghostly Matter is a typical metroidvania where mechanics borrowed from graphic adventures combine for an exciting genre crossover.
